**Curiosity Meets Probability: Decoding Community Solar Project Patterns** Over the past few years, solar energy has emerged as a central piece in the U.S. transition toward clean power. With pilot programs expanding nationwide and local governments allocating heritage funds to sustainable infrastructure, community solar projects are reshaping how Americans access renewable energy. A data analyst reviewing 45 real-world community solar initiatives posed a precise question: What is the probability that a randomly selected project—numbered from 1 to 45—is a multiple of 5 or 7? This seemingly simple inquiry reflects a growing trend: understanding patterns in clean energy adoption, supporting predictive modeling, and identifying insights buried within raw datasets. As communities scale, such analysis helps forecast resource allocation, equity distribution, and long-term impact. This article unpacks the math, context, and real-world relevance behind this probability question—and why it matters. --- ### Why This Question Is Resonating Across U.S. Energy Conversations
